LINE-JZEALKIIJG DEVICE.

Application filed June 12,

To all whom it may concern:

Be it known that I, GEORGE A. Kcninow, a

citizen of the United States, residing at Marquette, in the county of Clayton and State of Iowa, have invented certain new and useful Improvements in l'iino-Chalking Devices, of which the following isa specificat on. This invention relates to improvements in line chalking devices, such as are generally used by carpenters and others who use a chalk line.

One of the important objectsof the present invention-is to provide a line chalking device, wherein the holder for the chalk is of such a construction as toffaeilitate the chalkingof a line without theunnecessary "waste of the chalk, means being further provided for always holding the (3112, k in contact with a. line, while the same is being drawn through the device.

A still furtherobjectis'to provide a line chalking device of the above mentioned character, which is provided with a means fer guiding theline to the chalk by the device, thedevice being further provided with inc-ans whereby the chalk line may be disengaged therefrom.

A further obectof the invention is to provide a line chalking device of the above mentioned character, which is simple in construction, inexpensive, strong and durable, and further well adapted for the purpose for which it is designed.

Other objects and improvements in the details of construction, and in the combination and arrangement of parts may be re sorted to, without departing from the spirit of the invention and the scope of the appended claims.

In the accompanying drawing, forming a part of this application, and in which like reference characters indicate corresponding parts throughout the several views:

Figure 1 is a top plan View of the line chalking device en'ibodying my invention, and

Figure 2 is a view partly in side elevation and partly in section thereof.

In the drawing, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1. designates generally my improved line chalking device, the same comprising the base board 2, on which is adapted to be supported the substantially semi-spherical 1925. Serial No. 36,704.

son using the device to extend upwardly 60 therethrough and engage the bottom ofthe chalk for the purposes hereinafter to be more fully described. i

A wire guide ring '5 encircles the piece of chalk and is adapted to be supported in horizontal spaced relation with respect to the base board 2, so as to be spaced slightly from the upper face thereof 'in the manner as clearlyillustrated in Figure 2. The guide ring 5 is provided withthe lateral extension 6, the same being secured on the head 7 of a suitable bolt 8 which extends through the base board 2 at one end thereof. limit 9 is threaded on the lower end. of the bolt and engages the bottom' face of the base board, whereby the guide ring 5 :will be securely supported on the base board. Any suitable means may be employed for securing the extension 6 from the guide ring to the head of the post such as by soldering the same thereon. The lateral extension 6 terminates in the upwardly disposed portion 10, and the latter is then bent laterally to provide the spring supporting arm 11.

A coil spring 12 encircles the arm 11, and one end of the spring terminates in the downwardly extending portion 13, which is secured to the base board 2 as at 14. The opposite end of the coil spring 12 terminates in the forwardly extending portion 15, the end of which is bent to provide a loop 16, and forms a follower for engagement with the top of the chalk 3, as is clearly illust-rated in the drawing. The coil spring. 12 and the follower associated therewith will normally urge the piece of chalk 3 downwardly against the supporting base board 2, so that as the chalk is used up, the spring pressed follower will force the chalk downwardly, thus presenting a new surface to the action of the line.

In use, the line which is to be chalked is placed against the forward edge of the piece of chalk between the upper face of the base board 2, and the forward portion of the guide ring 5. The line is then moved against the piece of chalk, or else the line is held stationary, and the chalking device is moved along the same.

A line chalking device of the above men tioned character will save considerable time and labor and will furthermore eliminate the unnecessary waste of chalk, such as has been experienced with the methods now generally employed by carpenters in the chalking of lines. The opening 4 formed in the central portion of the base board 2 is used, when it is desired to raise the chalk, in order that the line may be disengaged from the device, after it has worn through the chalk and becomes interposed between the head of the bolts 7 and the adjacent portion of the chalk.

While I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape, and arrangement of parts may be resorted to, without departing from the spirit of the invention or the scope of the appended claims. 7

hat I claim as new is: a

1. A line chalking device of the class described comprising a base board, a line guide secured on said base board and adapted to encircle a piece of chalk supported on the base board, said base board having an opening formed therein, for facilitating the raising of the chalk from the base board, and a spring urged follower secured on the base board and engaging the top of the chalk for forcing the same downwardly against the base board.

2. A line chalking device of the class described comprising a chalk supporting base board, a ring like line guide enclrclmg the pleceof chalk, a lateral extension formed on the ring like guide, means for securing the same on said base board, said extension being bent upwardly and then laterally to provide an arm, a coil spring encircling said arm, one end of said coil spring being secured to the base board, the other end of said coil spring extending forwardly over the guide ring and terminating in a loop which isadapted for engagement with the top ofthe piece of chalk,said coil spring and said loop cooperating to force the piece of chalk downwardly against the base board.

3. A line chalking device of the class described comprising a chalk supporting base board, a ring-like guide adapted to encircle the piece of chalk, means for supporting said guide ring on one end of the base board, a coiled spring associated with the ringlike line guide, one end of the coiled spring being secured to the base board, the other end of the coiled spring extending above the guide rings and terminating in a loop which is adapted to engage the top of the piece of chalk, whereby the latter is forced downwardly against the base board.

In testimony whereof I afiix my signature.
